| 摘 要： | 于2008年采用植被常规调查方法,对磨刀溪干流3个引水式电站对河岸植物的影响进行调查研究,按影响情况,各电站设3个采样点.用植物生活型、物种多样性等参数,衡量小水电对河岸植物群落的影响.共采集到维管植物157种,其中乔木21种,灌木19种,草本植物117种.结果表明:各样地之间河流生境物理因子(流速、水深、底质类型、底质异质性)之间存在显著性差异;总的物种丰富度和草本植物的物种丰富度在各样地间存在显著性差异,乔木和灌木物种丰富度差异不显著;物种多样性方面,各样地之间差异性显著;湿生植物物种丰富度分析表明,小水电的修建,造成坝下样地湿生植物成分较低,与坝上样地和电站出水口样地有明显差异.研究认为,引水式电站的修建使河流河岸植被的连续性受到干扰,不利于河流生物多样性的保护.

| Abstract: | To understand the influence of dams on connectivity of riparian plant communities,three small hydropower plants from up-to-downstream of Modaoxi River were surveyed in September 2008.Plant samples were taken from the small hydropower plants,as well as at the upstream dams,downstream dams and downstream outfalls.Species richness and biodiversity of herbs and shrubs were determined in consecutive 1m2 quadrats and 25m2 quadrats,respectively,along a 50m long belt transect.157 plant species were recorded on a to... |
